Impact: 60 years of shock wave research at Sandia National Laboratories
Sandia National Laboratories physicists Mark Boslough and Dave Crawford predicted the Hubble Space Telescope would see a rising vapor plume as the Shoemaker-Levy 9 comet crashed into the far side of Jupiter in 1994. And sure enough, the plume produced by the impact matched Sandia's computational analysis. (2019-10-21)

12,800 years ago, thanks to fragments of a comet, humans saw an astonishing 10 percent of the Earth's land surface, or about 10 million square kilometers, consumed by fires. (2018-02-01)

NASA telescope studies quirky comet 45P
When comet 45P zipped past Earth early in 2017, researchers observing from NASA's Infrared Telescope Facility, or IRTF, in Hawai'i gave the long-time trekker a thorough astronomical checkup. The results help fill in crucial details about ices in Jupiter-family comets and reveal that quirky 45P doesn't quite match any comet studied so far. (2017-12-05)

Geologists exploring volcanic rocks on Scotland's Isle of Skye found something out-of-this-world instead: ejecta from a previously unknown, 60 million-year-old meteorite impact. The discovery, the first meteorite impact described within the British Paleogene Igneous Province (BPIP), opens questions about the impact and its possible connection to Paleogene volcanic activity across the North Atlantic. (2017-12-14)

Disruption tolerant networking to demonstrate internet in space
NASA's Human Exploration and Operations and Science Mission Directorates are collaborating to make interplanetary internet a reality. They're about to demonstrate Delay/Disruption Tolerant Networking, or DTN -- a technology that sends information much the same way as conventional internet does. Information is put into DTN bundles, which are sent through space and ground networks to its destination. (2018-07-16)

DNA of sperm taken from testicles of infertile men 'as good as sperm from fertile men'
Scientists have found that sperm DNA from the testicles of many infertile men is as good as that of ejaculated sperm of fertile men. This may explain a major cause of male infertility and opens the possibility of using sperm taken directly from the testicles of these men; to overcome their infertility. (2019-03-16)

A new way to see stress -- using supercomputers
Supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically. Widely-used atomic stress formulae significantly underestimate stress near stress concentrators such as dislocation core, crack tip, or interface, in a material under deformation. NSF-funded XSEDE-allocated Jetstream and Comet supercomputers simulate force interactions of Lennard-Jones perfect single crystal of 240,000 atoms. Study findings could help scientists design new materials such as glass or metal that doesn't ice up. (2018-11-30)

The glow of the Milky Way -- our galaxy seen edgewise -- arcs across a sea of stars in a new mosaic of the southern sky produced from a year of observations by NASA's Transiting Exoplanet Survey Satellite (TESS). Constructed from 208 TESS images, the panorama reveals both the beauty of the cosmic landscape and the reach of TESS's cameras. (2019-11-05)

A family of comets reopens the debate about the origin of Earth's water
Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans. Now, however, an international team, including CNRS researchers, has found that one family of comets, the hyperactive comets, contains water similar to terrestrial water. The study relies in particular on measurements of comet 46P/Wirtanen carried out by SOFIA, NASA's Stratospheric Observatory for Infrared Astronomy. (2019-05-23)

(2019-09-13)

ESO's VLT sees `Oumuamua getting a boost
`Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. This anomalous behaviour was detected by a worldwide astronomical collaboration including ESO's Very Large Telescope in Chile.

Second alignment plane of solar system discovered
A study of comet motions indicates that the Solar System has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from the Sun, tend to fall close to either the well-known ecliptic plane where the planets reside or a newly discovered 'empty ecliptic.' This has important implications for models of how comets originally formed in the Solar System. (2020-09-29)

When not seeing is believing
A year ago, astronomers identified the first interstellar visitor to our solar system. 'Oumuamua was studied by nearly every telescope available, including the ultra-sensitive Spitzer infrared space telescope. Despite a whopping 33 hours of observation time, 'Oumuamua proved too faint for Spitzer to see. Nevertheless, this allowed the observation team to draw significant conclusions. Their analysis of the visitor was published online on 14 November by The Astronomical Journal. (2018-11-16)

Wrong-way asteroid plays 'chicken' with Jupiter
For at least a million years, an asteroid orbiting the 'wrong' way around the sun has been playing a cosmic game of chicken with giant Jupiter and with about 6,000 other asteroids sharing the giant planet's space, says a report published in the latest issue of Nature. (2017-03-29)

Interstellar Comet with a Familiar Look
